Correct Answer: B

Rationale: The correct answer is B. Removing extra blankets from the crib is essential to prevent suffocation and reduce the risk of sudden infant death syndrome (SIDS). Extra blankets can pose a suffocation hazard to the baby during sleep. It is recommended to keep the crib free from loose bedding, pillows, and other soft items to provide a safe sleep environment for the newborn. Choices A, C, and D are incorrect. Placing the baby on his stomach (Choice A) increases the risk of SIDS. Padding the mattress (Choice C) can also pose a suffocation risk, and placing the crib next to a heater (Choice D) can lead to overheating, which is associated with an increased risk of SIDS.

Correct Answer: A

Rationale: Rubella immunization is recommended shortly after giving birth for a pregnant individual who lacks immunity. This timing ensures the client is protected from rubella in future pregnancies. Administering the vaccine postpartum allows the body to develop immunity without posing any risk to the developing fetus during pregnancy. Option B is incorrect because administering the rubella vaccine in the third trimester can potentially expose the developing fetus to the live virus, which is not recommended. Option C is incorrect as there is a preferred timing for rubella immunization in this scenario. Option D is incorrect as waiting until the next attempt to get pregnant does not protect the current pregnancy from rubella exposure.

Correct Answer: C

Rationale: An elevated temperature in a woman with ruptured membranes may indicate infection. Assessing the odor of the amniotic fluid can help determine if chorioamnionitis (an infection of the amniotic fluid) is present. This assessment is crucial to guide further interventions and management of the client's condition. Options A, B, and D are incorrect. Rechecking the client's temperature in 4 hours does not address the immediate concern of potential infection. Administering glucocorticoids intramuscularly is not indicated based solely on an elevated temperature. Preparing the client for an emergency cesarean section is premature and not supported by the information provided.

Correct Answer: C

Rationale: An L/S ratio of 2:1 indicates fetal lung maturity, as it signifies the presence of surfactant in the amniotic fluid, which helps with lung expansion and prevents collapse at the end of expiration. The absence of PG indicates immaturity of the fetal lungs, as PG appears in the amniotic fluid during the later stages of lung maturation. Biophysical profile scores and nonstress tests are assessments of fetal well-being and do not directly indicate fetal lung maturity. Therefore, choice C is the correct answer.

Correct Answer: D

Rationale: Encouraging the client to empty her bladder every 2 hours is essential during labor to prevent bladder distention, which can hinder labor progress and cause discomfort. A distended bladder can also lead to potential complications such as uterine atony or increased risk of infection. Choice A is incorrect as maintaining the client in the lithotomy position is not necessary during the active phase of the first stage of labor and may not be comfortable for the client. Choice B is incorrect because performing vaginal examinations frequently can increase the risk of introducing infection and disrupt the natural progress of labor. Choice C is incorrect as bearing down with each contraction is typically reserved for the second stage of labor when the cervix is fully dilated, not during the active phase of the first stage.
